Mathers Bradley, et al. Global epidemiology of injecting drug use and HIV among people who inject drugs, a systematic review. (2008).

Description

The number of countries in which the injection of drugs has been reported has increased over the last decade. The high prevalence of HIV among many populations of injecting drug users represents a substantial global health challenge. However, existing data are far from adequate, in both quality and quantity, particularly in view of the increasing importance of injecting drug use as a mode of HIV transmission in many regions.
